10. Phacelia Ivesiana'Torr. Ives Colorado Exp. 21. 1860. Diffusely much 

 branched from the base, 10-15 cm. high, hirsute-pubescent and glandular:

 toothed lobes, rarely bipinnatifid: racemes loose, 6-20-flowered: narrow ap- 

 pendages of the corolla adnate to the filament only at base: capsule oblong, 

 16-24-seeded. (P. campestris A. Nels. 1. c. 26: 242.) From western Wyo- 

 ming to southern California. 



11. Phacelia corrugata A. Nels. Bot. Gaz. 34: 26. 1902. Slightly glutinous 

 and more glandular-pubescent; stem branched or simple, moderately leafy, 

 terminating in elongated naked peduncles: leaves narrowly oblong, somewhat 

 alternately 11-15-lobed, the broad sinuses extending about halfway to the 

 midrib, each lobe with 2 or 4 rounded unequal lobes; petioles short or want- 

 ing: spikes very dense even in fruit: sepals linear-ob lanceolate, sparsely hir- 

 sute, nearly as long as the corolla: corolla blue, campanulate-funnelform, 1 cm. 

 or more long: stamens and styles nearly twice the length of the corolla; the 

 undivided base of the style pubescent: capsule elliptical, about 5 mm. long; 

 seeds oblong, obtuse at both ends. Utah, through Colorado to western Texas. 



12. Phacelia integrifolia Torr. Ann. Lye. N. Y. 2: 222. 1827. Annual or 

 biennial; stem very leafy, 1.5-5 dm. high: leaves -finely strigose-pubescent, 

 ovate-oblong or oblong-lanceolate, irregularly crenate-dentate, obtuse at the 

 apex, rounded or cordate at the base, 2y6 cm. long, petioled or the uppermost 

 sessile: spike-like branches of the scorpioid cymes dense, 5-10 cm. long when 

 expanded; flowers sessile, about 8 mm. long: calyx-segments acute: corolla 

 tubular-campanulate, white or blue, the tube longer than the calyx: filaments 

 glabrous, exserted: ovules 2 on each placenta. In saline soil; Kansas and 

 Colorado to Utah and Arizona. 



13. Phacelia sericea (Graham) Gray, Proc. Am. Acad. 10: 323. 1875. 

 Stems 1-3 dm. high from a branching caudex, silky-pubescent or canescent, 

 or the simple virgate stems and inflorescence villous-hirsute, rather leafy to 

 the top: leaves pinnately parted into numerous linear or narrowly oblong 

 lobes, these often again few-cleft or pinnatifid, silky-canescent or sometimes 

 greenish; the lower petioled; the uppermost simpler and nearly sessile: short 

 spikes crowded in a naked spike-like thyrsus: corolla violet-blue or whitish: 

 stamens long-exserted : capsule a little longer than the calyx. Mountains 

 of Colorado, Nevada, and northward.
